Smart manhole cover

　　With the acceleration of urbanization, the construction of municipal public facilities develops rapidly. The Ministry of Housing and Urban-Rural Development issued a Notice on Further Strengthening manhole cover Safety management, requiring urban water supply, drainage gas, heat, real estate, electric power, telecommunications, radio and television departments to implement digital manhole cover management to effectively supervise social resources and ensure people's personal safety.

　　According to incomplete statistics, the number of urban manhole covers in China reaches hundreds of millions of sets, covering tap water, street lamps, drainage, telecommunications, gas, heat, fire protection, sanitation, real estate, road construction and so on. In addition, the number of new and replaced manhole covers in the country every year at least 15 million sets. This means that the average number of manhole covers in each city is up to hundreds of thousands of sets, and the total annual increase and replacement of more than 20,000 sets. Most manhole covers still rely on inefficient traditional management involving tens of thousands of people.However, if the artificial inspection is replaced by intelligent means through science park, it can not only release more manpower for the society, but also further improve the efficiency of work. At the same time, the sensing equipment because of low power consumption, sustainable work for more than 5 years, intelligent manhole cover, but also can effectively reduce the cost of manhole cover management.

　　The intelligent manhole cover management and monitoring system can monitor and alarm the concentration of combustible gas, oxygen, hydrogen sulfide and other gases in the manhole cover to ensure the safety of personnel entering the manhole cover. It will upload the gas content, temperature and humidity to the monitoring center through the monitoring unit. When the concentration of harmful gases is too high, the monitoring system will alarm。

　　Since more than one kind of gas needs to be monitored under the manhole cover, multiple high-precision intelligent gas sensor modules must be integrated in the module. Gas sensors provided by the mining network include gas sensors and modules for combustible gas, oxygen, hydrogen sulfide, ammonia, carbon monoxide, methane, TVOC, nitrogen dioxide, formaldehyde, etc., providing an effective and reliable guarantee for environmental system monitoring in smart cities, smart factories and urban underground pipelines. With the acceleration of urban construction, the safety and functional requirements of manhole covers and manhole covers are increasingly high, and the intelligent manhole covers are an inevitable trend.
